SILAS L. TAYLOR, OF WILEYVILLE, WEST VIRGINIA.

WRENCH.

Specification of Letters Patent.

- Patented July 2o, 1921.

Application filed March 14, 1921. Serial No. 451,956.

To all wizom it may concern Be it known that I, SILAs L. TAYLOR, acitizen of the United States, residing at VVileyville, in the county ofWetzel and State of W est Virginia, have invented certain new and usefulImprovements in Wrenches, of which the following is a specification.

My invention relates to new and useful improvements in wrenches, and theprimary object of the invention is to provide a wrench which willautomatically adjust itself to any size nut to which the same is adaptedto be applied and which will also fit or grip any size pipe or rod towhich it is applied.

Another object of the invention resides in providing a wrench of thischaracter which is composed of few and simple parts and which will mosteii'ectively carry out the purpose for whichthe same is designed.

A still further object resides in providing a device which is simple anddurable in construction, inexpensive to manufacture and one which willbe very efficient in use.

In the accompanying drawing forming a part of this application- Figure 1is a plan view of my improved wrench with the jaws in open position;

Fig. 2 is a similar view with the jaws in closed position;

Fig. 3 is a perspective view of the sliding jaw with the wrench removed;

Fig. 4 is a similar view of the stationary jaw; and

Fig. 5'is a side elevation of the wrench.

In describing the invention I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which the numeral '1 designates a shankprovided with a sleeve '2, the outer end of said shank having what willbe termed for convenience a stationary jaw 3 thereon. Slidably receivedin the sleeve 2 is a shank 4; upon the outer end of which is formed an.additional jaw 5 which for convenience will be termed the movable jaw.The shank 4 is off-set adjacent the jaw 5 to provide a shoulder 6 whichabuts the outer edge of the sleeve 2 to limit the inward slidingmovement of the shank and the jaw.

The inner end of the shank 1 is curved outwardly to form a projection 7and pivotally connected with the inner end of the shank 4: is a link 8.A handle member 9 is prov ded, the inner end of which is somewhatY-shaped to provide the projections 1 and 11, said projections beingrespectively pivoted to the projection 7 and one end of the link 8.

Thus, it will be seen that the handle 9 has pivotal connection with theshank of the stationary jaw and also has pivotal connection with thelink, which in turn is connected with the slidable or movable jaw, andby a movement of this handle member 9 in one direction or the other thejaw 5 is moved outwardly or inwardly with respect to the stationary jaw3.

From the foregoing it will be seen that it is only necessary to move thehandle 9 in one direction to open the jaws and permit the same toreceive a nut, a pipe or other member therebetween, and by a movement ofthe handle in the opposite direction, these jaws are gripped against themember therebetween so that said member may be turned or acted upon asdesired.

While I have shown the jaws 3 and 5 fiat it will be understood that thesame may be corrugated or toothed if found desirable.

Thus it will be seen that I have provided a simple, inexpensive andeflicient means for carrying out the objects of the invention, and whileI have particularly described the elements best adapted to perform thefunctions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the principlesof the invention.

Having thus described my invention, what I claim is A wrench of theclass described, comprising a stationary jaw, a shank formed thereon andprovided with an elongated sleeve, the end of said shank opposite saidjaw being curved outwardly to form a projection thereon, a movable jaw,a shank formed thereon slidably arranged in said sleeve, a

handle member having its innerend portion designed Y-shaped to form apalrof projections, one projection of said handle member being pivotedto the projection on the first mentioned shank, and a link memberpivoted at its one end to the inner end of the second mentioned shankand pivoted at its opposite end to the other projection on said handlemember, whereby through oscillation of the handle member said movablejaw is disposed to its open and closed position.

In testimony whereof I afiix my signature.

SILAS L. TAYLOR.
